Bono and Chris Martin help raise $26 million for charity

Bono and Coldplay frontman Chris Martin helped raise $26 million for charity by singing at a star-studded auction in New York on Saturday.

The U2 frontman teamed with top designers Sir Jonathon Ive and Marc Newson to put together a collection of specially designed luxury items, from companies such as Hermes and Apple, for Jony and Marc’s (RED) Auction at Sotheby’s in Manhattan.

The event included a performance by Bono and Martin, who joined forces to sing a medley of U2′s “Beautiful Day” and Lou Reed’s “Perfect Day,” with the Coldplay star playing a custom-built red grand piano which was sold for $1.9 million.

Other items featured in the sale included a storm trooper helmet from the Star Wars franchise signed by George Lucas, which sold for $245,000.

The auction was attended by more than 1,000 guests including Harrison Ford, Meg Ryan, Courtney Love and Hayden Panettiere, and it raised around $13 million for Global Fund to Fight AIDs, Tuberculosis and Malaria.

The final total came in at around $26 million after executives of the Bill and Melinda Gates Foundation agreed to double the sales figure.
